So I recall seeing an article once, a long, long time ago (2+ years when the 8800GT first came out), where there was a small, physical alteration that could be made to the stock 8800GT fan, http://www.newegg.com/Product/Product.aspx?Item=N82E168..., that can decrease the temperature a little by cutting off a piece of the shroud. Anyone know of this article? I've been looking for an hour with no success. Thanks in advance.
If yu can't find it (the info about cutting off the shroud), why not just manually raise the fan through EVGA Precision settings? It's easier than taking out the card and getting the jig saw or dremel out.
Or if you don't want the fan noise, this 8800 GT VGA cooler has no shroud or fan!
I already have the cards, bios/volt modded to a 9800GT, my fan speeds are at 100% and it idles at 71c..I have two 9800gts (one a bios/volt modded 8800GT). I know how to raise fan speeds . Yeah. I need to clean out my cards and add new AS5, but I was wondering if anyone remembers the article...Thanks you though ^^.
Seems to me the shroud was engineered to direct the fan's airflow into the heatsink and fins. My dual MSI factory overclocked 9800 GTs in SLI also ran hot in idle and even with 90% fan speed while gaming I would get crashes when the temps got past 80s. I installed two case pans on the side panel to blow directly into the heatsink and fins (the MSI OC'd 9800 GTs had an "open shroud" design) and it solved the problem.
Due to the shroud design(there is no far distances to travel after exiting the heatsink its self) I see nothing that would help cooling too much. I know the 8800GTX with some cuts to the back plate could get better cooling by passing air easier.
The only thing i see is maybe making the fan hold a bit bigger since the blades are longer then the opening may help a bit.
Looking here you can see a slightly different shroud design. Pretty much cutting the shroud at the end of the heatsink and not leaving the perforated part. Would this help? No clue, but you may consider trying it. Also note the larger fan opening. Make sure you do not cut too big or the blower will not work right.
